Leib­niz-Zen­trum für Agrar­land­schafts­for­schung e.V. - HR

Die Mis­sion des Leib­niz-Zen­trums für Agrar­land­schafts­forschung (ZALF) e. V. als national und inter­na­tional agi­er­endes Forschung­szen­trum ist es, an der öko­nomisch, öko­lo­gisch und sozial nach­halti­gen Land­wirtschaft der Zukunft zu forschen – gemein­sam mit Akteuren aus der Wis­senschaft, Politik und Praxis. Das ZALF ist Mit­glied der Leib­niz-Gemeinsch­aft und unter­hält neben dem Hauptstan­dort in Müncheberg (ca. 35 Minuten mit der Region­al­bahn von Ber­lin-Lichten­berg) eine Forschungssta­tion mit weit­eren Stan­dorten in Dede­low sowie Pau­lin­enaue.

The pro­ject HAIR­phae (DFG) aims on study­ing the trade-off between root and mycor­rhizal absorpt­ive sur­face in response to soil nutri­ent stoi­chiometry. Plant eco­lo­gists have used eco­nomic the­ory to explain plant traits diversity from a resource acquis­i­tion point of view. The frame­work of the Root Eco­nom­ics Space includes the col­lab­or­a­tion gradi­ent that describes the plant reli­ance to sym­bi­osis with mycor­rhiza. The “out­sourcing” strategy within the col­lab­or­a­tion gradi­ent is char­ac­ter­ized by high root dia­meter, low spe­cific root lengths and strong mycor­rhizal sym­bi­osis. In con­trast, plants fol­low­ing the “do it your­self” strategy exhibit a fine acquis­it­ive root sys­tem but also a high root hair incid­ence and are less mycor­rhiza reli­ant.

This Bach­elor/Mas­ter pro­ject aims to test vari­ation in mycor­rhizal hyphae in the soil in response to land-use in man­aged grass­lands. The field-sampling has already been done and a com­pre­hens­ive sample eval­u­ation has star­ted to which the pos­i­tion advert­ised here is inten­ded to con­trib­ute by meas­ur­ing extrarad­ical hyphal length.

stu­dent assist­ant for 80h/month (f/m/d)

Com­bined with the oppor­tun­ity to con­duct a Bach­elor/Mas­ter's thesis on the acquired data, we are offer­ing a 4 month pos­i­tion start­ing in July at our loc­a­tion in Pau­lin­enaue as

Working field:

  • con­duct­ing labor­at­ory work on dried soils samples to determ­ine mycor­rhizal extrarad­ical hyphal length
  • ana­lyz­ing the vari­ation in rela­tion to plant spe­cies and land-use
  • eval­u­at­ing the res­ults with stat­ist­ical meth­ods


  • Major in bio­logy, soil, agri­cul­tural, or envir­on­mental sci­ences
  • interest in bio­lo­gical and eco­lo­gical aspects
  • patience with hand­ling micro­scopic samples
  • per­sever­ance to pro­cess a large amount of samples
  • know­ledge in the use of stat­ist­ical soft­ware (R)

What we offer:

  • an inter­dis­cip­lin­ary work­ing envir­on­ment that encour­ages inde­pend­ence and self-reli­ance
  • a col­legial and open-minded work­ing atmo­sphere in a dynamic research insti­tu­tion
  • a com­pany ticket for pub­lic trans­port
  • the oppor­tun­ity to con­duct a Bach­elor/Mas­ter thesis study­ing an aspect of per­sonal choice within the pro­ject
  • com­pany ticket
